The screenshot below shows the short final of an ILS approach. The horizontal CDI is centered (i.e., the aircraft is on the runway’s extended center line), and the vertical CDI shows the aircraft above the glide slope.

Note that if you fly a non-precision approach, then the vertical CDI will not be displayed. Also, the horizontal and vertical CDIs are not displayed when there is more than full-scale deflection.

i saw someone , Keith Smith from”pilot workshop” using it as a live on line assist to help
him navigate in near IFR conditions, or so it appeared. it seems as if you can open up “ google
earth “ and use a GPS to add info and your are good to go? sort of .
